The excited-state double proton transfer (ESDPT) process of dipyrido[2,3-a:3',2'-i]carbazole (DPC) in ethanol (EtOH) solvent is investigated using density functional theory (DFT) and time-dependent (TDDFT). computational results provide convincing evidence that did not occur spontaneously for the DPC monomer due to lack hydrogen bonds. Interestingly, after adding EtOH DPC, two intermolecular bonds were formed ground-state, strengthened excited-state, as confirmed by comparing changes primary...
The angular distribution of CH3I is investigated experimentally using a single Fourier transform-limited laser pulse and train, where 90-fs 800-nm linearly polarized field with moderate intensity 2.8×1013 W/cm2 used. dynamic alignment demonstrated in experiment. Moreover, train used to optimize the molecular alignment, degree almost identical that pulse. results are analysed by chirped femtosecond pulses, it demonstrates structure rather than its effective duration crucial alignment.
The adsorption properties of common gas molecules (CO, NO, and N 2 ) on the surface Li-decorated pristine graphene boron doped are investigated using density functional theory. energy, charge transfer, states three surfaces have been calculated discussed, respectively. results show that has strong interaction with CO . Compared graphene, exhibit a comparable ability Moreover, more significant energy to NO than because chemical molecule. between molecule substrate (Li-decorated graphene)...
Abstract In this work, we systematically investigate the effects of solvent on mechanism excited‐state proton transfer and photophysical properties 3NTF using density functional time‐dependent functional. The geometry (normal structure isomer structure) was optimized. Based optimized geometry, parameters related to hydrogen bond indicate that is strengthened in S 1 state. Further, reduced gradient functions provide a more intuitive proof excited strengthening mechanism. analysis frontier...
Abstract Background In view of the potential applications 10‐hydroxybenzo [h] quinoline (HBQ) in biological probes and organic light‐emission devices, excited state intramolecular proton transfer (ESIPT) mechanism HBQ was investigated theoretically work. Aims order to give a detailed reaction mechanism, ESIPT molecular system with hydrogen bond is systematically studied using density functional theory Methods Using (DFT) time‐dependent (TDDFT), we investigate photophysical properties...
A train of three equally spaced femtosecond laser pulses is employed to control the photoionization/photodissociation processes cyclopentanone. With increase pulse separation, a strong modulation product ion yield observed. More than ten-fold changes ratio between different products can be realized. The experimental observations further explain compositions and formation pathways peaks in mass spectra. controlling mechanisms are also discussed.
To explore the predictive value of combined detection serum interleukin-6 (IL-6), chloride (Cl-), D-dimer and fibrin degradation products (FDP) for severity acute pancreatitis (AP).From December 2020 to March 2022, 132 AP patients who met criteria inclusion were screened retrospective analysis from 292 admitted in emergency surgery at First Affiliated Hospital Zhengzhou University they divided into severe (SAP) group non-SAP group, with 63 SAP 69 according classification criteria. The data...
Abstract The photophysical features of 3‐(benzo[d]oxazol‐2‐yl)‐2‐hydroxy‐5‐methoxy benzaldehyde (BOHMB) were investigated through experimental (J. Phys. Chem. A 2019, 123, 10,246–10,253) and theoretical (Spectrochimica Acta Part A: Molecular Biomolecular Spectroscopy 2022, 266, 120,406) methods. However, the effect substituent groups on excited state proton transfer process has not been studied. In this work, intramolecular (ESIPT) dynamics properties BOHMB with different by...
